A weather'sealing member of extruded rigid vinyl material and comprising outer and intermediate parallel spaced flanges of uniform width and a web means interconnecting said flanges, the outer flanges having inturned beads adapted to seal against a panel edge at one side thereof, said web means having a surface adapted to seal panel edges at the other side thereof, said plurality of flanges having sealing edge faces adapted to seal against said frame member, and said web means having spaced ports adapted to receive a latch bolt means to adjustably position the panel in the frame.

MULTIPURPOSE WEATHERSTRIP coNsrnUcTroN BACKGROUND OF INVENTION Wall openings have been provided with window closure constructions including frame members defining a rectangular opening, the frame members being provided with vertical inwardly facing recesses for slidable reception of edges of window sash or panel members. in recreational and mobile home constructions the frame members for the opening have included extruded metal sections and the panel frame members have likewise included extruded metal sections dimensioned to be loosely received within the inwardly opening recesses in the opening frame members. In double-hung vertically slidable window sash or panels, weather sealing along vertical edges of the panels was' difficult to achieve while maintaining easy lifting of the panels for SUMMARY OF INVENTION The present invention contemplates a novel weather sealing arrangement which does not employ such prior proposed Weatherstrip devices as mentioned above but instead employs a rigid vinyl extruded Weatherstrip member receivable within frame recess means and serving several purposes. First, the Weatherstrip member of this invention provides a plurality. of longitudinally extending spaced parallel faces for pressure engagement with each frame member at locations deep within the recess means and therefore partially protected from both exterior and interior atmospheric conditions. Second, a panel is provided with panel edges, one edge having spaced longitudinal faces for slida'blesealing engagement with a smooth web surface on the Weatherstrip rnember at a protected location within a channel on a Weatherstrip member. On the other side, the panel edge is provided a sliding sealing gagement with said edge by reason of the inherent resiliency in the rigid vinyl flange material on which the surface is provided. Third, the weatherstrip member is provided with an asymmetric web means providing a deeper channel on one side than on the other side of the web means to afford convenient assembly and disassembly of the panel from the frame opening. Fourth, the Weatherstrip member may be provided with vertically spaced ports or openings in the web means for selective reception of a latch bolt member carried by the panel to adjustably position the panel in selected opened or closed positions.

The main object of the invention therefore is to disclose and provide a novel weatherstip construction for weather sealing space between a frame member and edges of a panel.

An object of the invention is to disclose and provide a novel multipurpose Weatherstrip member for such a weather sealing construction.

An object of the invention is to disclose and provide a Weatherstrip construction including means for weather sealing engagement at each panel edge along a plurality of protected longitudinal engagement faces on a Weatherstrip member.

Another object of the invention is to disclose a Weatherstrip construction in which means are provided to maintain pressure engagement of a plurality of weather sealing engagement faces provided on a weatherstrip insert member for a frame member.

A further object of the invention is to disclose and provide a novel Weatherstrip member which may be readily extruded from rigid vinyl material and which provides smooth sliding sealing surfaces for facilitating smooth convenient and easy raising and lowering of a panel guided between such Weatherstrip members.

Still another object of the invention is to disclose and provide a Weatherstrip member providing spaced port means adapted to cooperate with window latch means.

A still further object of the invention is to disclose a Weatherstrip member which facilitates assembly of a panel in a framed opening and which provides weather sealing means which are effective and have long life.

Various other objects and advantages of the present invention will be readily apparent from the following description of the drawings in which an exemplary embodiment of the present invention is shown.

FIG. 6 is a side elevationalview of a spring member used in the window construction shown in FIG. 1.

Referring first to FIG. 1 of the drawings, a window construction generally indicated at 10 exemplarily illustrates use of the invention in a double-hung sliding window arrangement. Window construction 10 comprises spaced vertical jamb frame members 11, a head member 12, and a sill member 14 joined together to provide a framed opening for a wall of a building or a recreational or mobile home vehicle. In the framed opening top and bottom panels 15 and 16 respectively are slidably vertically movable and adjustable to selected open positions. In this example each panel 15, 16 or window sash is provided with combination latch and handle means 17 having a construction and operation more fully described in my copending application Ser. No. 916,510 now U.S. Pat. No. 3,768,205.

In detail, each jamb member 11 (FIG. 2) may comprise an extruded metal section having an outer portion 20 and an inner portion 21 with laterally extending trim flanges 22 and 23 respectively adapted to bear against marginal surfaces of a wall 24 having an opening 25 within which the window construction is mounted. Inner jamb portion 21 may include an outwardly directed C-section 26 which adjustably cooperates with an inwardly projecting lip 27 on jamb portion 20 to provide adjustment of the two-part jamb member to walls of varying thickness.

Outer jamb portion 20 of suitable extruded crosssectional configuration comprises a longitudinally extending recess means 30 defined by a bottom wall 31 having a bottom recess surface 32 and side walls 33 having inner side surfaces 34. In this example wall 31 may be connected to trim flange 22 by a suitable web angle portion 36 and the innermost wall 33 may be extended laterally outwardly in the form of an angle section 37 to provide reinforcement and stiffness to the jamb member as well as a notch 38 formed with lip 27 to receive the outwardly projecting C-section portion 26 of the inner jamb portion 21. The jamb portions on each side of the opening are generally identical in construction.

Head frame member 12 (FIG. 4) may be formed of outer and inner head portions 40 and 41 respectively. Similarly sill member 14 includes an outer sill portion 42 and an inner sill portion 43. It should be noted that the cross-sectional configurations of the head and sill members 12 and 14 and their respective portions 40, 41, 42 and 43 are of the same cross-sectional configuration as that described above for jamb member 11, and for purposes of brevity, like parts of the head, sill, and jamb members will bear like reference numerals as indicated for the jamb members.

Each panel or window sash member 15 and 16 is also of similar construction and similar parts will be given similar reference numerals where possible, Panel 16 comprises vertical stiles or panel rail members 45 joined at their ends by a bottom rail member 46 and a top rail member 47. The rail members 45, 46, and 47 provide a continuous inwardly directed peripheral recess 48 within which a windowpane or window light 49 of suitable glass may be mounted as by molding or glazingreceptacles 50. Bottom rail member 46 and corresponding top horizontal rail member 46' of panel 15 may be constructed as described and claimed in my copending application Ser. No. l96,5l now US Pat. No. 3,768,205 for the slidable mounting ofa combination latch handle means 52. Top horizontal rail member 47 and its corresponding bottom horizontal rail member 47 on panel may each be provided with a generally dove-tail type groove 54 to receive therein a longitudinally extending interlocker Weatherstrip 55 of suitable vinyl material. Weatherstrip 55 includes a longitudinally extending Weatherstrip edge portion 56 which overlies the space 57 between rail members 47, 47' to seal said space when the window panels 15 and 16 are in closed position.

Bottom rail member 46 and corresponding top rail member 46' may also carry suitable Weatherstrip means 58 for sealing against the bottom recess surface 32 of the bottom wall of the head and sill portions 40 and 42. The weather sealing arrangements between the panels 15 and 16 and the head members and the sill members are known.

The present invention involves a novel concept of a sealing arrangement between the vertical jamb members and the opposed vertical edge means of the panels l5 and 16 and in which such sealing arrangement provides weather sealing, a means for readily slidably guiding the panels in their movement relative to the jamb members, and a means cooperable with the combination latch handle means for permitting convenient adjustable positioning of panels 15 and 16.

In this example of the invention, a longitudinally extending Weatherstrip member 55 is received within each recess means 30 (FIG. 2); each Weatherstrip member 55 includes the same cross-sectional configuration. Weatherstrip member 55 may be extruded to form strips of suitable length which may then be precut to the length required for a jamb member 1 1. Weatherstrip member 55 is preferably made of a rigid vinyl material presenting smooth surfaces. As seen in FIG. 5, Weatherstrip member 55 comprises a plurality of spaced parallel flanges of the same width throughout their length and including outer flanges 56 and an intermediate centrally located flange 57. A web means 58 extends transversely of said flanges for interconnection thereof and forming a double H-section. Web means 58 may be asymmetric to the edges of the flanges and defines therewith on one side of member 55 a pair of relatively shallow channels 59 and on the other side of member 55 relatively deep channels 60. Channels 59 and 60 face in opposite directions and are open throughout their length to receive therewithin longitudinal edge means 62 on stiles 45 of panel 16. Edge means 62 of the stiles 45 have a width less than the width of channels 59 and 60 and include edge walls 63 having edge faces 64 and side faces 65. Each 'outer flange 56 includes an inwardly directed longitudinally extending bead 67 extending into the opening to channel 60 and defining a space indicated at S (FIG. 5) which is approximately the width of edge means 62 so as to provide a sliding slightly interfering frictional fit between the faces 65 and the opposed surface 69 on central flange 57 and the bead 67.

It should be noted that Weatherstrip member 55 at the right of FIG. 2 is positioned in recess means 30 with the relatively deep recesses 60 facing wall 31 and with the shallow recesses 59 facing panel 16. The opposed or opposite recess means 30 has positioned therewithin a Weatherstrip member 55 with recesses 60 facing in the same direction as the recesses 60 at the right of FIG. 2. However, at the left of FIG. 2 recesses 59 face wall 31 of the jamb 11 and one of the recesses 60 snugly frictionally receives and grasps between bead 67 and the opposed face 69 on central flange 57 edge means 62 of panel in sealing relation. The space between the outer surfaces of the outer flanges 56 of weatherstrip member 55 is slightly less than the internal side surfaces 34 of recess means 30 so that member 55 may be slidably received within recess means 30. The width of flanges 56 and 57 is approximately the width of side surfaces 34 of side walls 33 of the recess means 30 so that the inwardly facing end edges of the flanges lie approximately in the same plane as that defined by the edges of the flanges when member 55 is received within a recess means 30.

Spring means 70 may be carried in spaced relation along edge means 62 of panel 16. Spring means 70 is carried only on the edge means 62 which is to be received within the relatively deep recess 60 asindicated at the left of FIG. 2. Spring means 70 may comprise a relatively short bearing foot 71 at one end and a relatively long bearing foot 72 at its other end, foot 72 being provided with a slightly outwardly turned end 73. Between the feet 71 and 72 the main portion 74 of spring means 70 is suitably curved to provide a sliding surface 75 of relatively shallow arc which bears against web means 58 as at 76. The shallow are 75 facilitates passage of the spring means 70 across one or more ports or openings 78 provided in web means 56 for reception of a bolt member 75 (FIG. 3) forming part of the combined latch handle means mentioned above.

It will thus be readily apparent that the arrangement of the panel '16, Weatherstrip members 55 on opposite sides thereof, spring means 70 on one side of the panel 16, and jamb member recess means provides a sliding panel construction wherein spring means 76 biases the adjacent Weatherstrip member 55 laterally to pro vide' longitudinal sealing engagement at 80, 81, and 82 between bottom surface'32 of bottom wall 31 and longitudinal edge faces of the flanges 56 and 57. Spring means 70 likewise laterally biases panel 16 sidewardly so that the walls 63 of edge means 62 of panel l6 longitudinally sealingly pressure engage at edge faces 64 of walls 63 the bottom surface of channels 59. The lateral biasing force also imparts sealing pressure engagement of the Weatherstrip member 55 at the right of FIG. 2 between the edge faces of flanges 56 and 57 and the bottom wall surface 32 of bottom wall, 31 as indicated at 84, 85, and 86. Thus, Weatherstrip members 55 are positively held in the jamb recess means 30 and pressure sealing engagement is provided to positively weather seal the space between the panel 16 and jamb member 11 and at the same time provide a tight non-rattling construction.

It will be apparent that at the right of FIG. 2 edge means 62 of panel 16 while providing pressure sealing engagement at 64 is provided relatively loose tolerance between the flange walls of recess'59. At the left of FIG. 2 the opposite edge means 62 is slidably fitted and frictionally grasped between bead 67 and surface 69 of central flange 57, the sliding interference fit being enhanced by the slight yieldability of the central flange The above description was made principally with respect to panel 16. ln FIG. 5 each Weatherstrip member 55 may be provided with ports 78 arranged'in web 58 along one channel 59 for a major portion of the height of'the panel to be received therewithin and similarly in the other corresponding channel 59 ports 78 are provided from the top of member 55 downwardly for a major portion of the panel height to be received in the upper portion of member 55. Thus, in this example, both panels 15 and 16 may be adjustably opened and positioned. In some installations it may be desired that one panel or the other panel may not be opened and for such installations bolt receiving ports 78 would be suitstrip member 55, sealing pressure engagement occurs between the web and the spaced edges of edge means 62.

The Weatherstrip member 55 may be utilized with other than double-hung sash panels and while vertically sliding panels are illustrated, it will be readily apparent that the weather sealing provided by the laterally outwardly biased Weatherstrip membersmay be used in horizontally sliding panels in certain environments Any modifications and changes of the weather seal construction described above which comewithin the spirit of the invention and which come within the scope of the appended claims are embraced thereby.
